About Delisle
Developed by French astronomer Joseph-Nicolas Delisle, the Delisle scale was created in the early 18th century. It is a backwards scale that has decreasing values as the temperature rises.
The freezing point of water is 150 degrees and the boiling point is 0 degrees. To convert a temperature from Delisle to Celsius, you can use the formula: Celsius = (150 - Delisle) * 2/3.
In the 18th century the Delisle scale was widely used particularly in Russia but has since been forgotten and replaced by the Celsius scale.
About Newton (temperature scale)
The Newton scale is a temperature scale that is now obsolete.
On the Newton scale the zero point is the freezing point of water and 33 degrees is the boiling point. This means that each degree on the Newton scale is significantly larger than a degree on the Celsius or Fahrenheit scales.
The Newton scale has been consigned to the history books but may be referenced in some (very) old textbooks.
